Patented Feb. 28, 1950 UNITEDA STATES PATENT FFICEv WASHING APPARATUSFon HOLLOW/WARE christopher Edmund Limit and Bernard. William'Downs,Hastings, England Application April 22, 1948, Seria1No'.-22,6'08 5claims. (ci. 15-211) This invention .relates to washing apparatus forhollow ware, such as glasses, tankards, mugs, milk bottles, jars and thelike, which apparatus is of thekindcomprising an upright-core extendingup through apertures in layers of ilexible material secured at theiredges to a frame, which flexible layers are provided with flexibleelements extending inwardly towards the core while the core has a numberof iiexible elements extendingoutwardly from it. In use, the assemblageis disposed in a vessel containing the washing liquid and'the hollowware is pushed up and downo-ver the core between the flexible elementson the' core which wipe the inside surface of the article and theinwardly directed flexible elements which wipe the outside or" thearticles. The object of the invention is to provide an improved meansfor mounting the aforesaid layers of exible material on the frame.

According to this invention, a washing apparatus of the kind referredtoisv characterised in that the peripheral edge of each layer ofA exiblematerial is gripped between two anges of a yring which is U-shaped incross-section with the bend of* the U directed outwardly, each ofwhichrings is mounted on said frame.. lor` example, each ring may be shapedsimilarly to a hollow truncated cone of small axial length with the bendbetween said limbs disposed at the greater diameter, each of which ringsis mounted on said frame so that its bend is lowermost. The aforesaidframe may comprise a number of upright arms disposed around and spacedaway from said core and having niches formed on their inner side inwhich said rings rest.

The aforesaid arms may be formed from metal strips which are secured attheir lower ends to a base which also supports said core and which armsare suiiiciently resilient to' enable them to be deected outwardly forthe insertion of said rings and means are provided for tying the upperends of the arms together after the insertion of the rings.

The aforesaid tying means may comprise one of said rings whichissupported by the outside of the llpper extremities of said arms andsecured thereto by clamping screws or the like.

The lower ends of said arms may be bent inwadly and secured toa metalplate to which said core is also attached, and a sucker has its upper Iarranged oe ove e 2 wall clamped between said plate and an under plate.

The following. is a description'of` one washing apparatus` accordingy tothis. invention, reference being made toV the accompanying drawings, in

which:

We claim:

1. A washing apparatus comprising an upright core, a number of flexibleelements extending out from said core, a frame encircling and carryingsaid core, a number of apertured spaced layers of flexible materialencircling the core and provided with inwardly directed flexibleelements a number of rings each of U-shaped cross-sec- -i thev upperends of the arms together after the tion and shaped similarly to ahollow truncated cone of "small axial length with the bend of the f Uarranged outermost. each of which rings encircles the periphery of alayer with the flanges of the U gripping opposite sides of the layer,said frame being provided with seatings for the afore'- said rings andmeans for retaining said rings on their seating.

2. A washing apparatus comprising an upright core, a number of flexibleelements extending out from said core. a frame comprising a number ofupright arms disposed around and spaced away from said core and securedat their lower en'd to said core, a number of apertured spaced layers offlexible material encircling the core and provided with inwardlydirected ilexible elements, a

ring of U-shaped cross-section encircling the pe- Ir'iphery of eachlayer with the flanges of the U gripping the opposite sides of thelayer; said up- `r ,right arms of the frame being provided withinsertion of the rings.

4. A washing apparatus comprising an upright l`.` core, a number offlexible elements extending out .from said core, a frame comprising anumber of ,upright ilexible metal arms, a base secured to the lower endsof the arms and supporting said yping oppositesides of the layer, saidupright arms being formed with niches into which the rings are adaptedto be sprung, and set screws clamping the outer ring to the extremitiesof said arms so asfi to tie them together and hold the other rings inposition.

5. A washing apparatus comprising an upright core, a number of flexibleelements extending out from said core, a frame comprising a number ofIupright ilexible metal arms, a metal plate selayer with the flanges ofthe U gripping opposite slides of the layer, said upright arms beingformed with niches into which the rings are adapted to be sprung, andmeans for tying the upper ends of the arms together after the insertionof the rings, and a single sucker arranged on the other side of theplate and a clamping meansbeneath said sucker and secured to said plate.
